Abstract: 1,167,182. Composite fibrillary yarns. ALGEMENE KUNSTZIJDE UNIE N.V. 6 Oct., 1966 [6 Oct., 1965], No. 44676/66. Heading B5B. A synthetic fibrillary yarn consisting of a plurality of immiscible components distributed over the cross-section of the yarn, within the yarn, substantially as continuous threads, the components being formed as superimposed layers which extend in both directions to the periphery of the transverse cross-section of the yarn, is produced by using a mixing device having stationary guide means to divide the stream of each component into sub-streams and then to re-unite said sub-streams along a regular distribution pattern, so that the main stream is subsequently distributed over the various extrusion orifices such that a plurality of secondary sub-streams of each component passes through each orifice, and solidifying the product thus obtained. Preferably the yarn is enveloped in a thin sheath formed by one of the components, the sheath being applied by using an apparatus wherein the spinneret assembly consists of two plates placed with their extrusion orifices in line and wherein a chamber before the first plate and before the mixer is supplied with different spinning materials, and the chamber between the said plates is supplied with the sheath forming material. The yarns may consist of nylon 6 and polyethylene terephthalate with a nylon 6 sheath or polyvinyl alcohol and polyacrylonitrile.

Abstract: 1388498 Gypsum calcination NATIONAL GYPSUM CO 28 Sept 1972 [17 Dec 1971] 44924/72 Heading C1A [Also in Division F4] Ground gypsum is continuously conveyed spirally through the length of a cylindrical heating zone solely by heated gases introduced into the zone and having a spiral motion imparted thereto by the introduction means, the gases heating the gypsum sufficiently to drive off chemically combined water, forming calcium sulphate hemi-hydrate. The heated gases are suitably injected tangentially into the cylindrical heating zone by passage through directional nozzles, and after leaving the zone may be reheated and recycled. In Fig. 1, gypsum powder from feed 34 passes via pump 36 into calciner cylinder 10. Gases heated at 42 flow up plenum chamber 16 and thence, via tubes 54 and 38 and inlet nozzle plenum 18, into calcining zone 20 through tangential nozzles 62. The calcined gypsum moves spirally down to exit 88. Tube 64 connected to fan 66 withdraws air from the centre of the calciner to be exhausted at 68 or recycled into plenum 16. Wet exhaust gas from 68 passes to a collector (not shown), where moisture and gypsum dust are removed.

Abstract: A block copolymer formed of a central copolymer block and two terminal monopolymer blocks is produced by polymerizing a mixture comprising (1) a conjugated diene and (2) a vinyl substituted aromatic hydrocarbon with an initiator which is the reaction product obtained by reacting lithium with a condensed-ring aromatic compound in a polar solvent, and in the presence of paraffinic, cycloparaffinic or aromatic hydrocarbons as diluent, the amount of said polar solvent present in the polymerization being less than 1.75 parts of polar solvent per 100 parts of said mixture of a conjugated diene and a vinyl-substituted aromatic hydrocarbon.  The conjugated diene is preferably 1,3-butadiene, isoprene or piperylene and is present in an amount of from 40-85 parts by weight of the mixture. A long list of suitable vinyl substituted aromatic hydrocarbons is supplied. The diluent is preferably a hydrocarbon which contains 3 to 12 carbon atoms. To produce the initiator system at least 2 gram atoms of lithium per mol of the condensed ring aromatic compound, which may be naphthalene, anthracene or phenanthrene or an alkyl derivative thereof is employed. The reaction is conducted in a polar solvent preferably an aliphatic monoether which has the formula ROR wherein is an alkyl radical containing from 2-12 carbon atoms at a temperature of from -40 DEG F. to 40 DEG F. A preferred initiator system is obtained by reacting lithium with a condensed ring aromatic compound and a conjugated diene in an amount of from 0.05-5 mol. of the diene per mol. of the aromatic compound. The initiator is used in amounts of from 1-5 millimoles per 100 grams of the monomer to be polymerized. The polymerization is carried out at a temperature of from -20 to 150 DEG C. and at a pressure sufficient to maintain the polymerization mixture in the liquid phase. The resulting polymer consists of a central copolymer block and two terminal homopolymer blocks consisting of the polymerized aromatic hydrocarbon. Specification 888,624 is referred to.

Abstract: 458,114. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. June 14, 1935, No. 17139. Convention date, June 14, 1934. [Class 106 (i)] Controlling printing of zeros.-In cash registers, accounting and similar machines, means for suppressing zeros to the left of the highest significant figure comprises means whereby the disabling of a zero stop pawl to permit adjustment of a differential disables the zero stop pawl of next lower order. Each key bank for non-additive data is provided with a zero stop pawl 46, Figs. 1 and 2 that, when not disabled by the depression of a key in the bank or otherwise, holds the differential arm 48 in zero position and controls the printing of asterisks from a type-wheel, Fig. 3. The stop pawls of the various banks are interconnected by studs 97 and lugs 98 projecting laterally in opposite directions from the pawls, the arrangement being such that when a pawl is disabled by the depression of a key in its bank, all the pawls associated with banks of lower denomination are also disabled. Thus if no key is depressed in a bank of lower denomination, the differential arm will rock through a full excursion and position the zero on the type wheel for printing. The stop pawls are controlled by the keys 39 of the associated bank through a cam plate 41 that, upon the depression of a key, interposes a stud 90 between a bail 92 and a cam surface on the pawl, so that upon the rocking of the bail by a cam 95 at the beginning of a machine operation, the pawl is rocked to ineffective position.

Abstract: 991,071. Automatic speed control. LOEWE OPTA A.G. Nov. 25,1963 [Nov. 27,1962], No. 46404/63. Heading G3R. The speed of an electric motor is stabilized by a centrifugal switch 27 which is closed when the speed is below a rated value to prevent a circuit comprising transistor 11, capacitor 12, and induction coil 13 from oscillating. This stops a signal being sent from the coil 13 through diode 26 to the base of transistor 6 which is rendered conductive to energize the motor. A rise in speed causes opening of switch 27 whereby the oscillator operates to block the transistor 6. The centrifugal switch 27 is coupled with the feed-back path of the oscillator circuit through capacitor 35 having one fixed plate and another plate which is mounted on the motor shaft.
